Overview

The NZXT H5 Flow RGB ATX Mid-Tower case is built around one central priority: keeping your components cool. Its perforated front and top panels allow a continuous flow of filtered air to pass directly over your hardware, a critical advantage for systems running high-wattage processors and graphics cards. Two pre-installed F140 RGB Core fans connect to a standard 5V ARGB header, delivering effective cooling from the moment you power on while adding vivid, customizable lighting to your build. A dedicated angled 120mm fan mount beneath the GPU area draws cool air from below, providing targeted cooling for your graphics card — an increasingly important feature as modern GPUs push higher thermal limits.

Beyond airflow, the H5 Flow RGB is designed with builders in mind. The interior supports ATX, Micro-ATX, and Mini-ITX motherboards, and offers up to 400mm of GPU clearance to accommodate large cards like those in the NVIDIA RTX 40 Series. Liquid cooling enthusiasts can mount up to a 280mm radiator in the front and a 240mm radiator on top. Cable management routing keeps the interior tidy, and the tempered glass side panel lets you display your work. Whether you are assembling a high-end gaming rig or a productivity-focused workstation, the H5 Flow RGB provides a well-ventilated, visually striking foundation that does not compromise on expandability.
